RVOLVER Rim Brake Front Hub QR

The RVOLVER introduces an unprecedented, patent-pending hub technology that goes so far beyond common buzzwords like “lightweight” and “easy-to-maintain,” that “revolutionary” is a better fit. Like nothing ever seen before, radial pawls in the freehub body engage a floating ratchet ring with a less than 15° engagement angle to react instantly to pedaling force without losing velocity.

“Floating” the ring lowers friction when coasting so you can roll farther on accumulated momentum. Connecting the ratchet ring to the hub shell without threaded parts significantly lowers RVOLVER’s weight, and sealed bearings and fewer internal parts make it the easiest hub to install and maintain so that even the most novice mechanic will be undaunted. The RVOLVER will revolutionize bicycle hubs.
